Zodiac – Internal lower rear float – R0841900

The Zodiac R0841900 is the genuine OEM internal lower rear float designed specifically for the Polaris Quattro P40 and Quattro Sport pressure-side automatic pool cleaners. Positioned at the lower rear section of the cleaner’s internal frame, this float plays a critical role in balancing the unit as it moves through the pool. Without correct buoyancy distribution at the rear, the cleaner would struggle to maintain proper orientation and traction against pool surfaces.

Floats of this type work by providing a controlled upward force at a precise point on the cleaner body. This counteracts the weight of the cleaner’s mechanical components and ensures the unit maintains the correct angle of attack as it navigates the pool floor, walls, and waterline. The internal mounting means the float is protected from direct abrasion against pool surfaces, contributing to a longer service life compared to externally mounted buoyancy components.

Technical characteristics and function

The R0841900 float is engineered to exact buoyancy specifications matching the original equipment installed in the Polaris Quattro P40 and Quattro Sport cleaners. Its internal rear lower placement is deliberate: by generating lift at the back of the cleaner, it helps the front drive section maintain downward pressure and grip on the pool surface, enabling effective wall climbing all the way up to the waterline. This wall-climbing capability is one of the defining performance features of the Quattro Sport platform, and a worn or damaged rear float will directly reduce this ability. The component is a direct drop-in replacement requiring no modification, and it is designed to match the original factory tolerances of the cleaner’s internal housing.

Suitability and application

This float is intended exclusively as a replacement spare part for the Zodiac Polaris Quattro P40 and Quattro Sport pressure-side in-ground automatic pool cleaners. It is suitable for in-ground pools of varying shapes and sizes where these cleaner models are in use. If your Quattro Sport cleaner is exhibiting poor wall-climbing performance, failing to maintain proper orientation on the pool floor, or visibly listing to one side, a deteriorated or missing rear lower float is a common cause. Replacing it with the genuine Zodiac R0841900 restores factory-specified buoyancy balance and full cleaning performance. This part is not compatible with other Polaris or Zodiac cleaner models and should only be used as specified.
